Authorities in northern Arizona had a mess on their hands after a truck crashed on a major highway, spilling a river of liquid chocolate onto the road surface.

The incident on Monday occurred on Interstate 40, about 11 miles east of Flagstaff.

There is a river of chocolate blocking/flowing in the westbound lanes of I-40 at milepost 211, east of Flagstaff. A tanker truck carrying 40-thousand gallons of liquid chocolate rolled over. This will be a sweet cleanup! pic.twitter.com/G03eVdNQZD
